计算今天，本周，上个月和[MySQL查询]的访问次数

Question

大家好，这是我表格的简化版本：

我想对这个表做四个mysql查询。所有这些都必须计算 id_user 等于某些特定值且类型与点击不同的总访问次数>。一个查询必须计算今天的访问次数，另一个查询必须计算本周，月份和总访问次数。我不是MySQL的专家，我当然可以使用PHP解决这个问题，但我更喜欢把负载放在我的sql server上。谢谢你的帮助！

Answer 1

放手一搏。我不知道你的桌子叫什么，所以我推荐它为trafficTable：

-- Visits today
select count(*) as visits_today
from trafficTable tt
where tt.type != 'click'
and tt.id_user = '19d71'
and datetime >= curdate();

-- Visits this week
select count(*) as visits_this_week
from trafficTable tt
where tt.type != 'click'
and tt.id_user = '19d71'
and yearweek(datetime) = yearweek(curdate());

-- Visits this month
select count(*) as visits_this_month
from trafficTable tt
where tt.type != 'click'
and tt.id_user = '19d71'
and year(datetime) = year(curdate())
and month(datetime) = month(curdate());

-- Total visits
select count(*) as total_visits
from trafficTable tt
where tt.type != 'click'
and tt.id_user = '19d71';

--- if you want the last month - this help other ppl in other thread
    select count(*) as visits_this_month
    from trafficTable tt
    where tt.type != 'click'
    and tt.id_user = '19d71'
    and year(datetime) <= year(curdate())
    and month(datetime) <= month(curdate());

您可能需要查看此页面：

功能month()，date()，curdate()，week()以及其他一些功能应该可以解决问题
